You'd think so but look how fierce it got in the Blizzard Entertainment vs KeSPA case in terms of copyright infringement and broadcasting StarCraft in terms of OSL, MSL, MST, and ProLeague. The only thing that was keeping Blizzard from collecting fines awarded by the church was the Ministry of Culture (Korean government office) while the US office saw it as fair grounds.

Blizzard Entertainment only caved (and didn't do an injunction during the trial process) was because they knew they would lose a massive chunk of customers in South Korea as well as a good handful internationally.

Laws of Fair Use only prohibit the use of copyrighted material for personal gain in any way, shape, or form.

As far as I know, any person on Youtube who is NOT a Youtube Partner (Being paid by Youtube per video per watch) can use any music or footage they wish to insofar as it is not an advertisement for a personal service/product or otherwise meant to accrue monetary gain. The only reason such a fit is being thrown is because the music industry is failing (Not because of illegal file sharing, but because of an utter lack of talent and literally no incentive to purchase rather than download for free).

The fact the Music Industry tends to make scapegoats of old ladies and little girls only encourages further illegal distribution (Who wouldn't want to harm a corporation that backhands old women and beats little girls, figuratively speaking?).

Basically, the only thing the Music Industry has is a sty to stew in when their ill-gotten gains are swept from under their fattened bellies and the artists decide to self publish and set their own bar (When the big record labels make at least ten to one what the artists make, you know it's a failure of an industry in every way).
